摘要： Electrically conductive masking tapes include an electrically conductive backing and an electrically conductive pressure sensitive adhesive layer. The pressure sensitive adhesive contains an acrylate-based copolymeric matrix, a crosslinker, an electrically conductive filler, and at least one antioxidant. The acrylate-based copolymeric matrix is the reaction product of a polymerizable mixture including at least one first alkyl(meth)acrylate monomer with a homopolymer Tg of less than -50°C, and at least one hydroxyl-functional alkyl(meth)acrylate with a homopolymer Tg of less than -10°C. The electrically conductive tape is capable of being laminated to and cleanly removed from a substrate surface, after being subjected to harsh conditions such as plasma vapor deposition conditions.

摘要： An electrically conductive multilayer stack(100) includes a first polymeric layer(110), an electrically conductive layer(120) bonded to a first side(112) of the first polymeric layer(110), and a second polymeric layer(130) disposed on an opposite second side(114) of the first polymeric layer(110). The first and second polymeric layers(110, 130) and the electrically conductive layer(120) are substantially coextensive with one another. When the multilayer stack(100) is wound to form a flexible closed loop(200) with the electrically conductive layer(120) forming an outside layer of the closed loop(200), the closed loop(200) regains at least about 80% of its initial diameter after a force compressing the closed loop(200) across the initial diameter by at least about 80%is removed, and the closed loop(200) regains at least about 70%of its initial diameter after a compression force per unit length of the loop(200) of about 0.8 kgf/cm compressing the closed loop(200) across the initial diameter is removed.
